Setting up a SSAS pension takes a trust deed, trustees, a scheme administrator and HMRC registration, which TPR says can take up to six months.
A small self-administered scheme is built in a set order, and the order matters because tax relief only starts once HMRC has registered the scheme. This page follows HMRC and The Pensions Regulator (TPR) step by step. Whether a SSAS suits your company is a separate question. Placing a SSAS beside your other pensions is something an FCA-authorised adviser does with you; a SSAS conversation can start from the form on this page whatever stage your plans have reached.
The steps, in the order they run
- The sponsoring company and the people who will be members are settled.
- A trust deed and rules are drawn up.
- Trustees are appointed.
- A scheme administrator is appointed under the rules and registers as such with HMRC.
- The scheme administrator applies to register the scheme with HMRC online, and HMRC decides.
- Once HMRC has registered it, the scheme is registered with TPR.
- Money is paid in and invested within the tax rules, not before registration if tax relief is wanted.
Until HMRC confirms registration, contributions "will not qualify for tax relief", and GOV.UK adds that a transfer in from another registered scheme counts as an unauthorised payment. How relief works is in pension tax relief, and moving an existing pot in is in how to transfer a pension. Fees and what a SSAS can hold are covered in SSAS providers.

The trust deed, the rules and the trustees
MoneyHelper's SSAS guide (archived 15 October 2025, so check the live page) says you need to be a company director to set one up, usually with a regulated adviser's help, and that you then decide who joins, which can include other employees and family members. Who qualifies is covered in SSAS for limited company directors. TPR's trustee toolkit (2018) describes a small scheme as trust-based and designed for up to 11 members, often directors of the sponsoring employer.
Tax law does not prescribe a legal form, HMRC's manual says, though most registered schemes are set up under trust. The deed that creates the scheme comes with rules covering the type of benefits, how they are funded, when and to whom they may be paid, and how funds may be invested. The documents must provide for appointing a scheme administrator and cannot entitle anyone to unauthorised payments.
The investment wording matters from the start. Under Schedule 29A of the Finance Act 2004, an occupational scheme with 50 or fewer members is investment-regulated if a member, or someone related to one, is or has been able to "direct, influence or advise on the manner of investment" of its assets, which describes a SSAS whose member-trustees choose the investments. Residential property and tangible moveable property, subject to exceptions, then bring tax charges. The practical detail is in SSAS providers, SSAS commercial property and, for lending to the sponsoring company, borrowing against a pension. Investment values can fall as well as rise, so the scheme could get back less than was paid in.
In a SSAS the members are typically the trustees too, jointly responsible for running it under the deed and rules, and a trust-based scheme's assets are held apart from the employer's. Their duties are set out in SSAS trustees and administrators.
The scheme administrator: a tax role with a test attached
The tax role of scheme administrator is not the same thing as a firm calling itself a SSAS administrator, though one can fill the other. Section 270 of the Finance Act 2004 defines it as whoever the scheme rules appoint to carry out the administrator's functions. HMRC's manual says it can be an individual, an organisation such as the employer or a specialist administration company, or a mixture; where more than one is appointed, each is jointly and severally liable for the administrator's tax charges and penalties. The administrator must be resident in the UK; before 6 April 2026 residence in an EU or EEA state was also accepted.
Before applying to register the scheme, the administrator registers as one on the Managing Pension Schemes service, as an individual, a company or a partnership. The declarations GOV.UK lists include being a fit and proper person and intending to carry out the role's functions and responsibilities at all times. GOV.UK, Register as a pension scheme administrator (updated 6 April 2026)
The fit and proper test (PTM153000) starts from an assumption that appointees qualify unless information calls it into question, and there is no advance check: HMRC "does not offer a clearance service". Factors that can count against someone include lacking sufficient working knowledge of pensions and pensions tax law "or does not employ an advisor with this knowledge", and being a disqualified director or bankrupt. The same guidance accepts that directors acting as administrator normally lack detailed pensions tax knowledge, and expects them to employ an adviser, such as a pension practitioner or provider, who has it.
Registering with HMRC, and how long it takes
HMRC's manual sets out the application. Only the administrator can make it, and only once the scheme has been set up, though that can be before any contributions are paid or members join. It goes through Managing Pension Schemes and "cannot be made in paper form", as an online form plus a set of declarations. GOV.UK lists what the administrator needs, including names, addresses and National Insurance numbers for the directors and trustees, and the establisher's company registration number, PAYE, Unique Taxpayer Reference and VAT numbers. A saved application must be finished within 28 days, and each incorrect or inaccurate statement can bring a penalty of up to £3,000.
Drafting the deed has no standard timescale; it depends on who prepares it. For HMRC's decision there is "no time limit", but if HMRC has not decided within six months of receiving the application the administrator can appeal to the tribunal as if it had refused. TPR's registration page says it "can take up to six months for HMRC to complete their checks". Relief runs only from the registration date, and "registration cannot be backdated". Timing the first payment and any transfer against the registration date is a question for the administrator; a wider look at your position can start by submitting the form on this page.
What HMRC decides, and what happens next
HMRC "must decide to register the pension scheme unless" one of a list of grounds applies. They include materially inaccurate information, a false declaration, an administrator who is not a fit and proper person and, for an occupational scheme, a sponsoring employer that has been dormant for a continuous month in the year before the decision (Finance Act 2004, section 153). HMRC, PTM032200 (updated 12 May 2026)
Progress shows online: the status reads pending, with a note when HMRC needs more information, and changes to open, with the scheme's Pension Scheme Tax Reference (PSTR), once HMRC decides to register. The registration date is the date of that decision. A refusal comes with a notification giving the reason, and an appeal should be made within 30 days of it. HMRC may still check after registration and can de-register a scheme from a later date.
After HMRC: registering with TPR and the scheme return
TPR will not take a registration until HMRC has registered the scheme. HMRC then passes the details on, and TPR emails one of the contacts it holds, in most cases the administrator who made the HMRC application, with eligibility questions that should be answered even if the trustees think registration is not needed. A workplace scheme with more than one member must register. The clock is three months from when the scheme first qualifies; late registration can bring a fine, and the levy has to be back paid. The Pensions Regulator, Register a pension scheme (published 29 September 2023)
After that the trustees set up levy payments and must tell TPR when registrable details change, such as the employer's or a trustee's name or address and the number of members. Scheme returns arrive by notice, and TPR aims to allow six weeks for each. For a defined contribution scheme the return is due every three years with between two and 11 members, and every year with 12 or more. A trustee who has "failed to take all reasonable steps to secure compliance" may be liable to a penalty, and HMRC's own scheme return is a separate thing.

Questions about setting one up
How long does it take to set up a SSAS pension?
No official source gives a total. HMRC has no deadline for deciding, though an undecided application can go to the tribunal after six months, and TPR says HMRC's checks can take up to six months.
Can I set up a SSAS pension online?
The HMRC part is online only. The scheme administrator registers on the Managing Pension Schemes service and then applies there, once the trust deed has set the scheme up.
Do I get tax relief on money paid in before HMRC registers the scheme?
No. Relief starts from the registration date, which HMRC cannot backdate, so contributions received earlier do not qualify.
Your next step
Whether to start a SSAS at all depends on your company, your other pensions and your plans for the money. A regulated adviser's view earns its place at that point: trustees-to-be who list their SSAS plans in the form on this page get a call from an adviser firm, at no cost.
